Detailed Description
The utility model will be further described with reference to the accompanying drawings.
A double m-shaped steel strip for a metal wound gasket as described in figures 1 to 2 comprising a steel strip in a metal wound gasket formed by alternately winding a plurality of layers of steel strip and a plurality of layers of non-metallic filler strip, typically graphite tape. The steel belt comprises two bending parts 1 with m-shaped cross sections which are connected in a reverse way, and the two m-shaped bending parts 1 are respectively positioned at two sides of the steel belt, so that the two sides of the steel belt can be sealed against medium pressure in the corresponding direction.
The bending part 1 is formed by sequentially connecting three sections of C-shaped wave arcs, each three section of C-shaped wave arc comprises a middle C-shaped wave arc 2 and two side C-shaped wave arcs 3, and the middle C-shaped wave arc 2 is reversely connected with the side C-shaped wave arcs on two sides of the middle C-shaped wave arc. The C-shaped wave arcs facilitate sealing against medium pressure from the direction of the C-shaped opening, whereas the middle C-shaped wave arc 2 is opposite to the opening direction of the side C-shaped wave arcs, so that a single bend 1 can seal against medium pressure in different directions by means of different C-shaped wave arcs, so that medium pressure in both directions can be applied on each single side of the strip.
In one embodiment, as shown in fig. 2, adjacent side C-shaped wave arcs 3 on two bending portions 1 are oppositely arranged and directly connected, and adjacent side C-shaped wave arcs 3 on two bending portions 1 are combined to form an S shape.
In one embodiment, an intermediate transition portion 4 is disposed between the two curved portions 1, and adjacent side C-shaped wave arcs 3 on the two curved portions 1 are oppositely disposed and connected by the intermediate transition portion 4.
In one embodiment, two sides of the bending part 1 far away from each other are respectively connected with an outer extension part 5, and the joint of the outer extension part 5 and the side C-shaped wave arc 3 forms folding points, so that more folding points can improve the rebound rate of the steel strip. In another embodiment, the sides of the two curved portions 1 facing away from each other are not provided with the outer extension portions 5.
The shape of the two bending parts 1 is mirror symmetry, so that the rebound ability of the steel strip in two directions is equivalent.
The arc diameter of the middle C-shaped wave arc 2 is smaller than the side C-shaped wave arcs 3 on two sides of the middle C-shaped wave arc 2, the whole bending part 1 is equivalent to a C-shaped structure with a groove in the middle, if the arc diameter of the middle C-shaped wave arc 2 is equal to or larger than the side C-shaped wave arcs 3 on two sides of the middle C-shaped wave arc, the groove in the middle of the C-shaped structure is equivalent to overlarge, but the rebound amplitude of the whole bending part 1 is reduced, so that the arc diameter of the middle C-shaped wave arc 2 is smaller than the side C-shaped wave arcs 3 on two sides of the middle C-shaped wave arc on the same bending part 1, the whole bending part 1 can have larger rebound amplitude, and the metal winding pad is compensated when the metal winding pad is relaxed due to temperature or pressure change.
In one embodiment, the arc diameters of the two side C-shaped wave arcs 3 on the same bending part 1 are equal.
In one embodiment, the arc diameters of the two side C-shaped wave arcs 3 on the same bending part 1 are not equal.
Any two C-shaped wave arcs which are directly connected are in transition connection, and the C-shaped wave arcs in smooth transition connection have better rebound resilience.
